<h3>Band Arithmetic Operator</h3>

<p>The Band Arithmetic Operator is used to create new image sample values derived
    from existing bands, tie-point grids and flags.&nbsp;The source
    data is combined by an arithmetic expression to generate the target data.&nbsp;</p>

<p>Please refer to the
    <a href="../visat/ExpressionEditor.html">expression editor</a> documentation for the syntax and capabilities of
    expressions.</p>
